In speech interactions, people routinely reason about each other’s auditory perspective and adjust their manner of speaking accordingly by raising their voice to overcome noise or distance, and sometimes by pausing and ...

The present study examines the ability to comprehend speech presented at synthetically accelerated rates in an auditory display environment. We sought to determine whether listeners could accurately predict their own ...

The Virtual Audio Server (VAS) is a toolkit designed for exploring problems in the creation of realistic Virtual Sonic Environments (VSE). The architecture of VAS pr

Until recently, multiple speaker systems for Virtual Environment (VE) applications were limited to a few front and rear speakers. Utilizing the Virtual Audio Server (VAS) with a Vector Base Amplitude Panning (VBAP) algorithm ...

In three of the manipulations in a 2009 dual-task performance study, virtual auditory cues were used to alert participants to the onset of three kinds of decision events in the secondary, but more demanding of the two ...

The ability to monitor multiple sources of concurrent auditory information is an integral component of Navy watchstanding operations. However, this leads to attentionally demanding environments. The present study tested ...

In Navy command operations, individual watchstanders must often concurrently monitor two or more channels of spoken communications at a time, which in turn can undermine information awareness and decision performance. ...

To examine the plausibility of dynamically adjusting the sounds presented by an auditory display, a study addressing the effects of pitch shifting on the identifiability of a set of forty-one environmental sounds was carried ...

Concurrent voice communications workload has been identified as a pivotal issue for desired reductions in the size of Navy watchstanding teams on future platforms. Without effective augmenting technologies, real increases ...
